Do not worry. I understand perfectly, I am working on my first plugins ??
10,000 already, wow.
As for columns option, I agree with you and it is very good plugins and something complex to do. The idea is not to reinvent the wheel, rather what you say, something basic that allows showing, or not, the fields generated for post type for example.
If users want something more complex, they will always have that plugin as an option and very good.
I will review the Github documentation. I saw that in another post you commented the idea to another user who wants to minimize the css and js of the forms. It could be a good practice for me at home.
Greetings and thanks again
